摘要
针对目前国内煤矿地面预注浆工程中遇到复杂地层需要化学注浆时只能采用普通注浆泵,腐蚀损坏严重、不能满足流量的无级调节等问题,研制了适应千米级深井地面预注浆工况的无级调速、高压、耐腐蚀的ZBB J-300/35-H型注浆泵。该泵主要由变频器、电动机、减速箱、三缸泵、撬座、吸排管系及润滑系统等组成,具有流量大且能无级调节、压力高、耐腐蚀、体积小、质量轻、操作简便等特点,厂内性能试验表明,该泵能满足流量在0~300L/m in范围内无级可调,注浆压力达到35MPa的设计要求。
There are several problems including only common pump used,serious erosion damage,no flux stepless adjustment in chemical grouting at complex geological area.ZBBJ-300/35-H grouting pump with stepless frequency control,high pressure and anti-errosion for pre-grouting in 1000m deep mine.The pump mainly was composed of transducer,motor,gear box,triplex pump,suction pipe and lubrication system.It characterized with large flux,stepless adjustment,high pressue,anti-errosion,small volume,light mass and easy operaton.Quality test showed that this pump reached design requirement of stepless control at the range of 0~300l/min flux and 35MPa grouting pressure.
